In order to solve the problems of the technologies described above, reach the purpose of convenient treatment, this utility model, a kind of electrode that is used for the tumor electrochemotherapy is combined into one by negative electrode 1 and one group of anode 2, wherein, anode 1 movable set is in negative electrode 2, these group anode 2 phase antikathodes 1 can all shrink into negative electrode when inwardly shrinking according to certain radian around anode shaft mind-set outside sweep when extrapolated.
Further, described negative electrode 1 adopts hollow, the sharp keen round tube shape structure in lower end, and the insulation of outer wall top exposes the ring-type conducting metal in the outer wall lower end;
Further, described anode 2 top integral body are made insulation processing, and the lower end is made up of the many sharp keen elasticity pins 5 of end, and elasticity pin 5 one ends and anodic axle link together, and elasticity pin 5 ends expose conducting metal;
Further, the top of described negative electrode 1 and anode 2 is provided with the hands handle that makes things convenient for control electrode to insert;
Further, described negative electrode 1 outer wall surface is provided with the sign distance scale;
Further, to expose the width of ring-type conducting metal be 5mm in described negative electrode 1 outer wall lower end;
Further, the elasticity pin 5 most advanced and sophisticated exposed 2mm that many ends of the lower end of described anode 2 are sharp keen.
The beneficial effects of the utility model are, adopt the such electrode of this utility model, can treat more easily, only need once-through operation to treat, reduce the acupuncture wound, reduced the probability of complication and patient's the pain of injury, and accurately control electrode position and spacing; Guarantee accurate treatment simultaneously, guarantee that more firm fixed electrode organizes grappling well to be difficult for slippage under long-time treatment and respirometric influence, guarantee the degree of depth of electrode insertion and the accuracy of position; Can also reduce the electrode manufacturing cost.
Description of drawings
Below in conjunction with the drawings and specific embodiments this utility model is described in further detail:
Fig. 1 is the profile of electrode state before therapeutic electrode is inserted;
Fig. 2 is that therapeutic electrode is being inserted by the state profile after the treated tissue;
Fig. 3 is the outside drawing of electrode state before therapeutic electrode is inserted;
Fig. 4 is that therapeutic electrode is being inserted by the state outside drawing after the treated tissue.
The specific embodiment
By shown in Figure 1 be electrode state before the profile of electrode state before therapeutic electrode is inserted and the insertion shown in Figure 3 outside drawing as can be known, negative electrode 1 is a hollow, the sharp keen tubular structure in lower end, the surface of its lower end is a ring-type conductive surface 6, and the upper end has the handle 7 and the negative electrode that make things convenient for control electrode to insert to draw lead 3; Anode 2 is positioned at cathode tube intracavity portion, can move up and down along the negative electrode tube chamber, its front end is made up of the many sharp keen elasticity pins 5 of end by one group, convergent-divergent is in the tube chamber of negative electrode 1, wherein an end of many elasticity pins 5 and anodic axle weld together, face of weld should be handled smooth, and makes itself and anode shaft keep thickness consistent, and the upper end has the handle 8 and the anode that make things convenient for control electrode to insert to draw lead 4.
By shown in Figure 2 be therapeutic electrode insert the profile of rear electrode state and insertion rear electrode state shown in Figure 4 outside drawing as can be known, after electrode inserted, the front end of anode 2 stretched out from the tube chamber of negative electrode 1, one group of elasticity pin 5 of front end is similar to umbrella and opens;
When treating, in conjunction with related medical equipment, the position that needs treatment is inserted in the lower end that at first will make sharp keen hollow, round tube shape structure negative electrode, because negative electrode 1 and anode 2 integrators, anode 2 movable sets are in negative electrode 1, so, only need to insert once, can be easily the negative electrode 1 and the anode 2 of electrode be all inserted.Then, anode 2 is provided with the sign distance scale with reference to outer wall surface slowly to be released downwards outside the negative electrode 1 to suitable definite position, after anode 2 stretches out from negative electrode 1 tube chamber, elasticity needle-like 5 terminal can stretching, extensions according to its crooked in advance good shape, the radius of its stretching, extension is the distance of negative electrode 1 and anode 2, can in certain scope, determine the scope of treatment by stretching radius, because the upper end of negative electrode 1 upper end and anode 2 all is provided with the handle that makes things convenient for control electrode to insert, thereby guarantee that electrode can make things convenient for the on position and the degree of depth accurately, can be fixed in preferably by in the treated tissue owing to open anode tip 5 simultaneously, and be difficult for being moved, thereby better fixed electrode by the respiratory movement of therapist etc.At last, negative electrode is drawn the negative pole that lead 3 connects the treatment power supply, and anode is drawn the positive pole that lead 4 connects the treatment power supply, begin treatment.After treatment finishes, utilize handle that anode 2 is upwards drawn along negative electrode 1 tube chamber, anodic needle-like end 5 is collapsiblely to advance among the negative electrode tube chamber, can extract entire electrode smoothly.
In order to guarantee the better circulation of electric current, negative electrode 1 inwall is made into insulation, outer wall top is made into insulation, the lower end exposes the ring-type conducting metal, makes itself and anode 2 not conducting electric currents, preferably, only 6 places, lower end are made the ring-type conductive surface of 5mm, for making the electrodes conduct part with biological tissue chemical reaction not take place under "on" position, conductive surface uses the inert electrode material, as platinum or platinumiridio etc.Anode integral body is made insulation processing, and at elasticity needle-like most advanced and sophisticated 5 exposed 2mm, exposed part also adopts the inert electrode material.Elasticity needle-like tip is uniform distribution around anode shaft, can be made into different bending radius according to the treatment needs, to satisfy different therapeutic domain requirements, also can make the end of varying number simultaneously, to satisfy the requirement of different distribution of electrodes density.
By in imitated biological tissue experiment and the zooperal data that go out, this coaxial electrode with the control experiment of traditional electrical chemotherapy electrode in the effect of electrochemical reaction and suitable to the fragmentation effect of biological tissue, even be better than traditional electrode.In the simplicity of operation, cause wound because electrode inserts, and the assessment aspect of curative effect is better than traditional electrode fully simultaneously.
